TEAS test?

I'm taking the TEAS test next week, my score is worth 33% of my entry points towards getting into the nursing program here.
I've been studying out of the ATI pre-test study manual, but it's from last year and a new one has come out since. Do you think it makes any difference as far as what will actually be on the test? And if anyone has any pointers that would be great. I've got a great GPA, but so far my pre-tests aren't looking so hot!
Thanks in advance,
